Urgent need for contraceptive education and services in Chinese unmarried undergraduates: A multi-campus survey

Access to reproductive health services among the female floating population of childbearing age: a cross-sectional study in Changsha, China

Background

The floating population serves an important role in economic and social development. However, little is known about the floating population’s reproductive health (RH) services, especially in low- and middle-income countries. This study aimed to assess the use of reproductive health services in the female floating population in China, which is a country with the largest floating population in the world.

Methods

A cross-sectional survey was conducted for more than 3 months. Six hundred twenty females of childbearing age in a floating population were recruited into the study by using random sampling, with these individuals being recruited from six community centres in Changsha, China. The use of reproductive health services was assessed by utilizing a self-designed questionnaire.

Results

A total of 555 participants returned the completed questionnaires (effective response rate of 89.5%), including 405 married women and 150 unmarried women. The utilization of RH services was poor in individuals who could access RH policies (39.3%), RH education (36.4%), RH counselling (27.4%), gratis contraceptives (36.0%), and free RH examinations (38.9%), and married women utilized these services at higher rates than unmarried women (P < 0.01), although 63.3% of the unmarried women had sexual lifestyles. The marital status was significantly associated with receiving RH education, RH counselling, gratis contraceptives, and free RH examinations. Age was significantly associated with the use of RH education and free RH examinations. The average personal monthly income had a significantly beneficial effect on the use of free RH examinations. Obstetrics and gynaecological disease prevention (67.2%) were the greatest needs of the RH services, and the use of the Internet was the best way to obtain these services. Most of the individuals (77.3%) hoped to receive gynaecological health screenings that were provided by obstetrics and gynaecology hospitals.

Conclusions

The female floating population exhibited poor awareness of RH and rarely used RH services, especially in unmarried women. The results suggest that educational interventions for the female floating population, as well as policy and resource developments should meet the demands for RH services, which are urgently needed in China.

Contraceptive practices among unmarried women in China, 1982-2017: systematic review and meta-analysis

OBJECTIVE

Premarital sexual practices and contraceptive prevalence rate (CPR) among unmarried women in China remain unclear. We conducted a systematic review and meta-analysis to estimate CPR and analyse contraceptive methods used by unmarried women between 1982 and 2017.

METHODS

Wanfang, The China National Knowledge Infrastructure Database, MEDLINE, PubMed and Web of Science were systematically searched. Data on CPR and use of major contraceptive methods were extracted and pooled using a DerSimonian-Laird random effects model.

RESULTS

Of 188 articles retrieved from five databases, 22 studies met our inclusion criteria. Overall CPR based on a random effects meta-analysis was 32.2% (95% confidence interval [CI] 24.7%, 39.8%). Pooled rates of contraceptive use were 61.4% (95% CI 47.9%, 74.9%) for condoms, 25.9% (95% CI 14.5%, 37.4%) for pills, 19.8% (95% CI 8.9%, 30.8%) for the rhythm method and 25.4% (95% CI 14.2%, 36.7%) for the withdrawal method.

CONCLUSIONS

The sexual and reproductive health situation of unmarried women in China seems to have improved little since the 1990s. Our findings may help to optimise reproductive health care programmes and thereby reduce the alarming rates of unplanned pregnancies and abortions among unmarried women in China.

Association between condom use and perspectives on contraceptive responsibility in different sexual relationships among sexually active college students in China: A cross-sectional study

China has increasing incidence of unplanned pregnancies among college students these years. Increasing students' sense of responsibility to protect sexual partners may help reduce the rate of unplanned pregnancies.A self-administered questionnaire was distributed to students from 3 colleges in Sichuan, China. Among them, 559 of male students and 267 of female students were included in this study. The questionnaire collected participants' characteristics, usage of condom, and investigated male and female students' perceptions of who should be responsible for contraception use.We found that relationship status was closely related to students perceiving responsibility for reproductive health and condom using. Male students who were in casual relationships during their most recent sexual encounter and shared responsibility for contraception were more likely to use condoms than other male students (P < .001). Female students who were in steady relationships during their most recent sexual encounter and shared responsibility for contraception were more likely to use condoms than other female students (P = .007). The multivariate analysis revealed condom use was associated with greater odds of sharing responsibility for contraceptive use in different types of sexual relationships.Improving students' attitudes toward responsibility for contraception may increase condom use among students at risk for unplanned pregnancies. Programs providing targeted health education and services may help reduce the rate of unplanned pregnancies among students in China.

Association between factors related to family planning/sexual and reproductive health and contraceptive use as well as consistent condom use among internal migrant population of reproductive ages in three cities in China, based on Heckprobit selection models

OBJECTIVE

With the increased population mobility and the transition in population policy, scholars are quite concerned about family planning/sexual and reproductive health (SRH) and related factors among internal migrant population of reproductive age. Therefore, the proposed study was designed to explore the association between factors related to family planning/SRH and contraceptive use as well as consistent condom use among the above-described population in China.

DESIGN

Cross-sectional study.

SETTING

Three municipalities in China, namely Beijing, Shanghai and Chongqing.

PARTICIPANTS

Among the 6545 participants, 2099, 2414 and 2031 subjects came from Beijing, Shanghai and Chongqing, respectively.

RESULTS

A total of 6545 eligible participants were included as the full sample, 6188 of whom who had intercourse in the last 3 months were selected as the subsample. Among the subsample, 80.88% (5005/6188) adopted any form of contraceptive methods and 49.14% (3041/6188) consistently used condom in the last three sexual intercourses. Meanwhile, the involved participants had a better mastery of knowledge on SRH than on contraception (p<0.0001). The results of the Heckprobit models revealed that the factors associated with both contraceptive use and consistent condom use were relationship with the first intercourse partner, communication frequency with spouse/sexual partners on sex, actual number of children and knowledge on SRH, while knowledge on contraception and age at first intercourse were associated with contraceptive use and consistent condom use, respectively (p<0.05).

CONCLUSIONS

In the current study, we revealed a high-level contraceptive prevalence, a relatively low-level consistent condom use and a poor mastery of knowledge on contraception and SRH. The Heckprobit selection model specified the existence of selection bias, providing evidence on the association between the factors on family planning/SRH and contraceptive use as well as consistent condom use, respectively. Our findings indicated that health institutions should offer appropriate technology and high-quality family planning/SRH services for the internal migrant population in China.

Association between college health services and contraceptive use among female students at five colleges in Wuhan, China: a cross-sectional study

Background

College students have a high incidence of unplanned pregnancies in China, which has highly raised public attention. As such, numerous reproductive health services are provided to college students. This study examined whether health services in college lead to contraceptive use among female college students in heterosexual relationships.

Methods

A self-administered questionnaire survey with cross-sectional design was administered among female students in four colleges in Wuhan, China to identify health service factors associated with contraceptive use in the past 6 months.

Results

The analysis revealed that younger female students had lower odds of contraception use, whereas students who reported availability of health-related web sites were more likely to use contraceptives. Female students who reported that contraceptives and birth control counselling were accessible from college health services had greater odds of contraceptive usage. Finally, provision of contraceptives and birth control counselling from school were associated with greater odds of contraceptive use.

Conclusions

Contraceptive-related health services play an important role in reducing unintended pregnancies by directly addressing the contraceptive needs of female students. Programs that provide targeted services may help to reduce high rates of unexpected pregnancies among female students in China.

Unintended pregnancy and its correlates among female attendees of sexually transmitted disease clinics in Eastern China

This study is to determine the prevalence of unintended pregnancy and its risk factors among the female attendees of sexually transmitted disease (STD) clinics in Zhejiang Province, China. A self-administered questionnaire survey of a cross-sectional design was administered to attendees at four STD clinics in 2007. Of the 313 female STD clinic attendees, 42.5% reported that they had at least one unintended pregnancy; the induced abortion rate was 39.0%. Over their lifetime, 12.1% responded “use condoms always/often” and 5.4% “always/often used oral contraceptives.” The risk factors for the unintended pregnancy identified by the multivariate analysis were as follows: being married, experience of nonconsensual sex, and a history of STD, having two and over two sexual partners. Unintended pregnancies and induced abortion by female STD clinic attendees have reached an alarming prevalence. Doctors at STD clinics should attach importance not only to the STD problem of the female attendees, but also to the unintended pregnancy and the associated factors. Targeted contraceptive counseling and intervention should be promoted at STD clinics as a strategy to improve the efficiency and effectiveness of the reproductive health services in China.

A review of contraceptive practices among married and unmarried women in China from 1982 to 2010

OBJECTIVE

To analyse the contraceptive prevalence rate (CPR) among - and contraceptive methods used by - married and unmarried women in China, from 1982 to 2010.

METHOD

Data concerning married women were collected from national surveys conducted by the Chinese government. Those pertaining to unmarried women were obtained by searching the China Academic Journal Network Publishing database and PubMed.

RESULTS

CPR among married women in China was 89% in 2010, the highest in the world. Most married women use long-acting reversible contraceptives, particularly intrauterine devices, and sterilisation. CPR among sexually active unmarried women has fluctuated between 17 and 70% since 1988, although the frequency of condom use has increased (Cochran-Armitage trend test, χ(2) = 126.1, p < 0.001). More than 25% of unmarried women rely since at least 1982 on less effective contraceptive methods, including rhythm and withdrawal. This has led to an annual induced abortion rate of approximately 20% among those women.

CONCLUSION

In sharp contrast to the high CPR among married women, the rate among sexually active unmarried women in China has remained extremely low since 1988. More efforts should be directed at raising contraception awareness among this population to improve their reproductive health and reduce the rate of unwanted pregnancy.

Factors associated with condom use among male college students in Wuhan, China

Background

Using condoms consistently could prevent unintended pregnancy among young people. This study highlights multiple domains of influence on condom use among male college students in China, including knowledge, attitudes, health services utility on condom use and reproductive health information sources.

Methodology/Principal Findings

To identify factors associated with condom use in Chinese male college students, we examined a sample of 870 sexually experienced male students in seven colleges in Wuhan, China, 2009. 535 (61.5%) of 870 male students reported condom use during their most recent sexual encounter. Male students with steady partners were more likely to use condoms than students with casual partners (adjusted OR = 3.11, 95%CI 2.30–4.20). And positive attitudes toward contraceptive responsibility were associated with greater odds of condom use (adjusted OR = 1.40, 95%CI 1.02–1.92). Only 54(6.2%) and 83(9.5%) of respondents reported that free condoms and reproductive health counseling were available at the student health center. Providing free condoms and reproductive health counseling at the student health central were associated with increased condom use among college students (both P<0.05). In addition, students who gained reproductive health information mainly through websites, television and radio programs were more likely to use condoms than through school education (all P<0.05).

Conclusions

Improving attitudes of male students toward contraceptive responsibility, providing proper reproductive health information through mass media and making free condoms and reproductive health counseling available in school may help increase condom use among college students in China.

The effect of mahogunin gene mutant on reproduction in male mice: a new sight for infertility?

Mahogunin is an important mediator of chromogenesis and neurodegeneration. Mahoganoid is a mutation of the mahogunin gene, which causes a pleiotropic phenotype that includes suppression of obesity, spongiform neurodegeneration and improvement of insulin sensitivity. Our previous research found that mahoganoid widely expressed in the male rat reproductive system, and mahoganoid-deficient mice have reduced embryonic viability. But the reproductive change in mahogunin knockout (md(nc) ) male mice has not been reported previously. Here, we report that the mahogunin mRNA also widely exists in reproductive system of male mice, and its mRNA expression in the testis was in accordance with the first spermatogenesis wave cycle. Moreover, we find that md(nc) male mice were able to mate with females but no pups are delivered. Besides, the sperms' active progressive motility and hormone secretion (E2, FSH, LH, PRL) were obviously decreased while abnormal sperm rate showed no significant difference in md(nc) compared to wild-type (WT) male mice. This study indicates the mahogunin deficiency results in the infertility of male mice, disruption of hormones secretion and impaired active progressive motility, which may additionally illuminate the aetiology of male infertility in human.

A preliminary study of the relationship between the long arm of the Y chromosome (Yqh+) and reproductive outcomes in IVF/ICSI-ET

OBJECTIVE

To compare the reproductive outcomes of Yqh+-carrying and control couples undergoing IVF/ICSI treatments.

STUDY DESIGN

Retrospective analysis of 72 Yqh+ carriers and 986 Yqh+ non-carriers undergoing their first cycle of ART in a single centre between August 2005 and May 2011.

RESULTS

Yqh+ carrying couples had significantly worse reproductive outcomes compared with control couples undergoing IVF treatment. There were a significantly higher cancellation rate (20.69% vs 7.9%; P<0.05; OR, 3.03; CI, 1.18-7.79) and a significant lower fertilisation rate (50.05% vs 66.01%; P<0.05; OR, 0.61; CI, 0.49-0.57), implantation rate (8.33% vs 20.87%; P<0.05; OR, 0.35; CI, 0.14-0.87), good quality embryo ratio (44.70% vs 57.89%; P<0.05; OR, 0.59; CI, 0.43-0.80) and clinical pregnancy rate (17.39% vs 39.59%; P<0.05; OR, 0.32; CI, 0.11-0.96) in Yqh+ group compared with control group undergoing IVF treatment. Yqh+ carrying couples had similar reproductive outcomes compared with control couples undergoing ICSI treatment.

CONCLUSIONS

The Y chromosome polymorphic variant Yqh+ most likely plays a role in infertility. Yqh+ couples with poor reproductive outcomes in IVF treatment can be advised to undergo ICSI to improve their reproductive results in the next cycle.

Effect of pre-freezing conditions on the progressive motility recovery rate of human frozen spermatozoa

We evaluated the effects of sperm concentration, progressive motility, sperm morphology, duration of abstinence and collection season on the progressive motility recovery rate of human frozen spermatozoa to identify characteristics that predict the progressive motility recovery rate of human frozen spermatozoa and improve the protocol for sperm collecting in sperm banks. A total of 14 190 semen samples donated at Zhejiang human sperm bank of China between September 2006 and June 2011 were collected from 1624 donors. Semen was evaluated according to WHO standard procedures for sperm concentration. Progressive motility, sperm morphology, ejaculate collection season and abstinence time were recorded. After freezing and thawing, the progressive motility was assessed. Results showed that sperm concentration, progressive motility and normal morphology were significantly associated with the progressive motility recovery rate of human frozen spermatozoa. In addition, the abstinence time and collection season also significantly affected progressive motility recovery rate. Our results indicated that sperm concentration, progressive motility and normal morphology could be valuable in predicting the progressive motility recovery rate of human frozen spermatozoa. As such, progressive motility recovery may be improved by donating semen when abstinent for 3-5 days and during seasons other than summer.
